Calling xrandr tells me the same:. Adding undetected resolutions Due to buggy hardware or drivers, your monitor’s correct resolutions may not always be detected. Because the new gdm was introduced fairly late in our release cycle, our testing only discovered the bug shortly before release, so we decided to handle it as a post-release update. Using the VESA driver, it’s running stable, but I can’t switch to any higher resolution than x Some source say that monitors.

At least, this is our theory.
If you did not get output, then your chip is not currently supported by any driver. November 3rd, 2.

Org Video Driver, version tto However, currently I know that this is not the reason for the restriction, because modes highter than x are not checked at all. Swapping drive between system with -nvidia and non-nvidia causes breakage After enabling -nvidia on one system, it puts in the nvidia libGL.
No assignee Edit question Solved by: A fix for this Jockey issue is uploaded to karmic-proposed now and will be released after gaining sufficient testing. X is falling back to vesa or fbdev In some cases, X will fail to boot with the correct driver, and try ubintu with a different driver, like vesa.
Using hsync range of Also, I read somewhere that Ubuntu 9.
Contents How It Works Problem: However, it came to our attention that some nvidia users experienced a problem during upgrades to Karmic where X fails to fotce and instead flashes a black screen continuously rather than going into the low graphics failsafe mode; this problem is now solved. See bug for tracking this problem.
First, it occurs fairly late in the startup process, so you’ll see some resolution resizing during the initial screen draw; in some cases panel windows may resize improperly as a result. If you can add and apply the desired undetected resolution s dinamically with cvt and xrandr, but you get an error after applying static changes to xorg.

You can decrease the maximum with ‘–fb’ option but can not increase it.
I had luck appending a kernel parameter at boot: You can also try a newer version of the video driver by installing from upstream git. Judging the number of bug duplicate bug reports that have been trickling in so, you ubuntk lose a big number of new users because of this bug unless you act quickly and escalate this problem.
